To all whom it may concern:

Be it known that I, EDWARD MnNnnLsoHN, a citizen of the United States, and resident a of New York, in the countyof New York 5 and State of New York, have invented certain new and useful Improvements in.

Methods of Treating Silk Stockings, of which the following is a specification.

The main object/of this invention is to give tothin silk stockings a more sheer appearance and at. the same time to increase the strength and durability. By the use of my improved process various other important objects and advantages are secured,

. certain of which will be hereinafter reof soap in the solution is probably about 5 of 1%., The soap reacts with the alum to form an insoluble metallic soap within and around the fibers forming the silk threads. As a result of this treatment, the fibres going to make up the threads are brou ht in more compact relationship; the loose fi re ends are caused to adhere to the body portion of the threads and the threads are thereby reduced in efi'ective size and made harder and more compact. The compacting of j, the fibres also tends to increase the strength of the individual threads and permits them to slide over each other during the bending or stretching of the fabric. It also increases the elasticity. The elimination of the loose or. flufiy ends of the fibres also reduces the liability of the fabric being threads, the stockings are removed and treated with a soap solution; the percentage torn in case any sharp objectrubs against Application filed April 4, 1,924. Serial No. 704,292.

' it, or where under strain as for'instance,

at the garter clasps. The insoluble metallic arcane soap forms a very thin coating over the threads which is not removed by later washings and therefore the dye in the threads is preserved and there is less liability of fadmg by repeated washings. The coating also protects the threads against. the action of perspiration.

I am aware that it has 'been proposed to deposit insoluble metallic. soap on cloth to render the same waterproof, but in my improved process, the sheer silk is rendered 'even less water-proof because the individual threads are rendered more compact and of smaller-effective size, and the openings between the threads are thereby enlarged rather than closed-up or plugged. This 1s important in. connection with thin silk stockings, as sheer appearance and ventilation are both desired.

Having thus described my invention, what ll claim as new, and desire to secure by Letters Patent, is: 1

1. The process of treating silk stockings appearance, which consists in ,subjecting them to the action of an alum solution and to render them stronger and more sheer in thereafter subjecting them to the action of the soluble soap solution.

2. The process of treating silk stockings which consists insubjecting them to an ac-' tion of solution containing approximately 5% of alum and thereafter subjecting them to an action of a solutionxcontainingapproximately of 1% of soap.

3. The herein described method of treating silk fabrics to increase the strength, durability and sheer appearance which consists" in subjecting them to the action of relativelystrong alum solution and thereafter subjecting them to the action of a relatively weak soluble soap solution, to hardenr and compact the threads and thereby increase the size of the apertlrres between the threads.
